There were no function on control panel

The hardest part of the repair was trouble shooting the problem. Not recommended for the DIY. Buy removing all the housing screws and then removing the touch pad under the front cover ,Disconnecting the two wire connectors, I was able to remove the touch pad for replacement.
After receiving the new part it was a matter of reversing the order to install the new part and checking the operation. In my case everything works. P.S I took a wild guess that it was the circuit board touch pad.
